YHE BP Doctor is a novelty in the world of smart watches that can measure blood pressure, oxygen saturation and changes in heart rate. The watch uses the “patented automatic cuff inflation method”, which allows the device to take measurements that do not differ in accuracy from medical equipment. In addition, smart watches allow you to measure not only blood pressure, but also heart rate variability – cardiogram. These data can be used, for example, to assess the level of stress. Also, using the device, you can analyze sleep patterns and the level of blood oxygen saturation. The watch is equipped with a 1.4 – inch touch screen AMOLED – display with a resolution of 320×360.
